A schoolbag

Abstract

The invention relates to a schoolbag which comprises an inner hard frame, a flexible schoolbag cover which covers the frame, and two braces which are connected with the frame. The frame comprises an L-shaped base composed of a vertical plate and a horizontal plate. The base is provided with an object placing groove. The side part of the object placing groove is vertically slidably connected with the vertical plate, and the bottom part of the object placing groove is elastically connected with the horizontal plate. The storage groove is an upwardly open U-shaped groove, and a plurality of partitions are vertically spaced in the storage groove so as to partition the internal space of the storage groove into a plurality of storage units. The sliding rail is vertically arranged on the inner side wall of the vertical plate, and the placing groove is slidably connected with the sliding rail through a sliding block. A plurality of compression springs are arranged on the cross plate at intervals, and the bottom of the storage groove presses against the top of each compression spring. The invention has the advantages of simple structure, high space utilization rate, convenient use and easyburden.

Description

technical field [0001] The invention relates to a school bag. Background technique [0002] Heavy schoolbags have brought great burden to primary and middle school students and outdoor travellers. Especially primary and middle school students who are in the growth and development stage use schoolbags every day. Although the burden reduction of primary and middle school students has been advocated all the time, various books, exercise books, and test papers can often still fill up the schoolbag, increasing the weight of the schoolbag and causing disorder in the schoolbag. [0003] The main shortcoming of existing school bag is analyzed below. [0004] Disadvantage 1) There is often no suitable partition design in the existing schoolbags, which makes the internal space utilization rate of the schoolbags low. Books, test papers, etc. are often stacked directly at the bottom of the schoolbags, which is inconvenient to take and causes the overall center of gravity of the school...

AI Technical Summary

Problems solved by technology

[0004] Disadvantage 1) There is often no suitable partition design in the existing schoolbags, which makes the internal space utilization rate of the schoolbags low. Books, test papers, etc. are often stacked directly at the bottom of the schoolbags, which is inconvenient to take and causes the overall center of gravity of the schoolbags to move down, increasing the moment, which increases the burden on the shoulders

[0005] Disadvantage 2) When the schoolbag is carried, it mainly relies on the shoulders to bear the weight. The reason why the schoolbag feels heavy is that when walking, the shoulders of the person do not move horizontally, but do ups and downs, and the schoolbag as a whole will follow the person. The body shakes up and down, which adds an extra burden to the shoulder straps, especially when going up and down slopes or going up and down stairs.

Existing schoolbags do not have a buffer or force unloading device for this problem, so that the straps continuously impact the shoulders of the person during the carrying process, so that the shoulders not only bear the weight of the schoolbag, but also bear additional impact force
